Your idle jet 65 and holder orifice 100 (idle air jet) are what you tune for light throttle economy.
Your choice depends on where your mixture screws are now. 3/4 turn out is a good starting point.
Try a 60 with the same 100 first. If you need more 1.25 turns out, then stay with 65, and step the air up to 110, then 120 if necessary. You should use a wideband 02 sensor and data logger if you are able to.
Your cam is a nice mild lopey grind for a street car.
I think the engine could go better up the top end with a 38 venturi, possibly even up to 40mm.
